A rotary liquid filler is an industrial machine designed to fill containers with liquids in an automated and efficient way. These machines are widely used in various industries, such as food, beverage, chemical and pharmaceutical products, to fill liquids into bottles, jars, containers or packaging. They play a fundamental role in large-scale production, allowing precise, hygienic and rapid filling of liquids. Here is how a rotary liquid filler generally works and what it is for:
Product feeding: The liquid to be filled is fed into the machine from specific storage tanks for the product. The product can be preheated or cooled as needed to maintain the desired viscosity.
Container preparation: Empty containers, such as bottles or jars, are loaded into the machine via a conveyor belt or conveyor system. These containers can be sterilized and positioned appropriately to receive the liquid.
Container positioning: Containers are positioned at filling stations, which are part of the machine rotation.
Filling: While the containers are positioned at the filling stations, the liquid is dosed and inserted into the containers in a controlled and precise manner. This can be done through different filling methods, such as piston dosing, pump dosing, or other dosing systems specific to the type of liquid. Precision in filling is essential to ensure that each container contains the correct amount of liquid.
Sealing: After filling, containers are hermetically sealed with lids, seals or seals. The machine applies the caps or seals and screws, presses, or seals them, depending on the type of cap and the specific machine.
Quality inspection: Filled and sealed containers are often subjected to automated inspections to ensure product quality, such as checking seal integrity, dosage consistency, and possible contamination.
Coding and labeling: Many machines have coding systems to print information such as expiration date, production batch and other relevant data on containers. In addition, they can apply labels with information about the product.
Final packaging: After the filling process, individual containers can be grouped into larger packages, such as boxes, pallets or other types of packaging, as required.
One of the distinguishing features of rotary fillers is the rotation of the filling stations, which allows multiple bottles or containers to be filled at the same time, increasing process efficiency compared to linear machines that operate on a single row of containers. These machines are essential in various industries to ensure the mass production of high-quality packaged liquid products consistently and efficiently.
There are several types of rotary fillers for liquids and pasty products, each designed to meet the specific needs of different products and industries. Below, I will list some common types of rotary fillers for liquids and pasty products:
Rotary filling machines for liquids:
Piston fillers: They use pistons to accurately measure and dose liquids. They are frequently used in the food and beverage industries for products such as juices, milk, oils, syrups, among others.
Peristaltic pump fillers: Use a peristaltic pump to transport liquids and are suitable for products sensitive to contamination, such as pharmaceuticals and biotechnology products.
Gravity fillers: Allow liquids to flow by gravity in containers, suitable for liquids with low viscosity.
Rotary fillers for pasty products:
Piston fillers for pasty products: Similar to piston fillers for liquids, but designed for products with high viscosity, such as sauces, pastes, creams and jellies.
Screw fillers: Specially designed for pasty products, these machines use a screw system to dose and fill products such as toothpaste, cosmetic creams and other high viscosity products.
Lobe pump fillers: Use lobe pumps to dose and fill pasty products, including food products and high-viscosity chemicals.
Plunger or rotary plunger fillers: Use rotary plungers to dose pasty products, such as pharmaceutical gels and high-viscosity cosmetic products.
Each type of rotary filling machine is designed to meet the specific needs of liquid or pasty products, considering their viscosity, density, volume and filling characteristics. The choice of the appropriate machine depends on the characteristics of the product to be filled and the production requirements of the industry in question. Regardless of the type of filling machine, they all aim to provide efficiency, precision and hygiene in the filling process. |
